The invention relates to a toothed chain (1) with alternating inner and outer chain links (2, 3), joined by means of a chain joint (4), wherein the inner chain links (3) comprise at least one inner plate (7) and at least two joint bushes (10) running perpendicularly through the above, the outer chain links (2) comprise at least two outer plates (5) and at least two joint pins (6) running perpendicularly through the same. To form a chain joint a joint pin of the outer chain link (5) extends through a joint bush of the inner chain link and at least one inner plate (7) of the inner chain link and/or at least one outer plate of the outer chain link is embodied as a toothed plate with each having two teeth defined by an outer flank and an inner flank. According to the invention, a toothed chain with improved life and improved design for the complete chain drivetrain can be achieved, wherein an outer flank angle given for both outer flanks of a toothed plate (5,7), is E >= 65° and <= 75° and the ratio VBa between a pitch T of the toothed chain (1) and the outer diameter dBa of the joint pin is <= 2.65.
